Top failures
Coil spring fractured or broken 6.72%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Rigid brake pipe excessively corroded 4.32%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
CV joint boot split or insecure 3.36%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Wiper blade not clearing windscreen 3.36%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 3.17%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp beam pattern obviously incorrect 3.17%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Common advisories
Tyre worn close to legal limit (19.29%) · Brake pipes corroded and greasy (14.88%) · Brake disc pitted or scored (14.49%) · Slight play in steering rack joints (13.34%) · Engine oil leak, not excessive (11.8%) · Tyre slightly damaged or cracking (8.93%)
